    The tension bar was added to solve this very problem. The lack of break angle at the bridge is the culprit. A taller action would help, as would higher gauge strings.

    I realize one would be reluctant to significantly alter a nice vintage guitar but you might try and find an original tension bar from an Astro or Corvette. Failing that, a Towner tension bar would work well.

    Would a different bridge be better englishman, for instance with a straight bridge at least if it pops out it is still sitting on amsurface rather than in between the space controls rollers

    Isn’t a ‘64 supposed to have the retainer bar, or were some produced without it?

    If you don't want to modify the guitar, you can try filing a deeper string slot in the bridge as you suggest. I had the same problem when I removed the tension-roller Bigsby from my 5620 and replaced it with a B6. The problem disappeared after I filed deeper slots in the bridge.

    From the photo, I can't tell whether your bridge is floating or fixed. If it's fixed with bushings, you can try a Towner Down Tension Bar II, which sits on the bridge posts and doesn't require drilling. Just double-check the post spacing to make sure it fits.

    Doesn't look like there's too much of a break angle. A better bridge couldn't hurt, but the real culprit is that trem. A tension bar would cure that.

    Never really dealt with a space control bridge. A straight bridge would still make the string sharp since it's not sitting in the groove.

    My corvette had the same problem since the tension bar was missing. I fixed it by running the strings under the trem bar instead of over. It disables the trem but the break angle is much better. This is a good option if you don't want to alter the guitar any.

    Get a new bridge while you're at it too. ;-) Compton's are the best.

    Bridge base seems to be fixed in position, though space contol part rocks as you move it

    They come without slots but you have to add them yourself.

    The Towner Down Tension II needs a bridge that's screwed into bushings in the guitar. It sits under the thumbwheels and needs something holding it down; otherwise the strings will pull the bridge up off of the guitar.
